CAR STAKEJ Application med August 12.1927. Serial No..212,5 77.

This-invention relates to improvements in car stakes and. moreparticularly to telescopic car stakes for flatand ,gondola railway cars.I

Tllheprimary-object of the invention is to provide a telescopic carstake which is ex tron-rely simple and durable in construction as'vvellas'eflicient in use.

Another object is to provide animproved telescopic car stake embodyingsimple and efficient means for releasably maintaining thewsame in:extended condition.

Aafurtherobject; isto provide an improved telescopic caretake of theabove kind having simple. and efficient lmeans whereby the load bindingchainsmay be readilyadjusted to the heightof theiload.

-Gther objects-willbecome apparent as the nature of the invention isbetter understood, and the same-consists in the novel form,combinationand arrangement ofparts hereinafteiumore fullydescribecLwshown in the accompanying-drawings and claimed.

- In the; drawings, wherein like reference characters indicatecorresponding parts throughout the several views,

Figure 1 is a fragmentarylongitudinal section of a gondola car equippedwith a telescopic stake constructed in accordance with the presentinvention the stake being in extended condition and shown in sideelevation as seen looking toward the inner sides thereof;

Figure Q isafI' agmentarv transverse section taken upon line 2--2ofFigure 1;

Figure 3v is a vertical section taken upon line 3-8 of Figure 2;

Figure .4 is a view similar to Figure 3 wit-lathe stake. n collapsedcondition; and

Figure .is an enlarged horizontal sec tion taken upon line..55 of Figure1..

Referring more-in detail to the drawings, the present car stakesincludestelescopically associated lower and upper sections 5 and 6. preferablyin the nature of open-ended rigidmetallictubes of rectangularcross-section as shown inlFigure 5. whereby relative turning ofthesectionsv will be prevented.

The upper'seetion lower section 5 and has pairs of opposed horizontalsliding catch bolts 7 mounted in the lower end portion thereof. Asshown. the pairs of catch bolts are mounted in spaced superimposedrelation, and the inner ends of the bolts of each pair are operativelyconnected by toggle links 8, the adjacent 6 slidably fits into thepivotally connected ends of which are pivoted to a-vertical operatingrod 9 thatproects upW-ardlyin the upper stake section 6 and terminatesnear-the upper end of. the

latter in a handle 10. Each pair of latch;

bolts is slidably mounted in a casing ll-suitably fixed within the stakesection :6 and enclosing helical tension springs 12 which act tonormally project the. latch bolts through the opposite-side ofthe stakesection 6. As shown, the inner ends of the latch bolts are-providedwithoppositely proecting lateral extensions 13 towhich the inner ends of thesprings 12 are. attached, the outer ends of the springs .12 beingsuitably attached to the outer ends of the casing 11. In view of .theabove construction it will be seen that by pullingupwardly upon the rod9,-ithe toggle links 8 will be broken in an upward direction so as toeffect vthe retraction or release of both pairs of lock ing bolts, whileupon releasing the rod 9-,

' the springs .12 -wi1l act to straighten. the

toggle links, lower rod 9 and project bolts 7.

Provided in opposite sides of the lower stake section are pairsof spacedsuperim posed openings 14 outwardly into which the latch bolts 7 areadapted to be projected when the upper stake section 6 is elevated toextended or operative position. When the bolts 7 are thus projected intothe open.- ings 14, it Will be evident that the upper stake section iseffectively maintained in its elevated operative position. By employingtwo pairs of opposed locking bolts in spaced superimposed relation, amost effective latching engagement with the lower section is had and theupper section is effectively braced against lateral strains andaccidental release. Any suitable means may be provided for fasteningthe'stake to the car and for preventing movement of the section 6entirely-out of section 5. but as this forms no spociticpart of thepresent invention disclosure thcreof is refrained from herein.Obviously, the stake may be applied to the outer side of the sill of aflatbottom car, but as shown, thesame is mounted at the inner side ofthe side. wall'14 of a gondola car.

In order to exclude the entrance of dirt and other foreign matter intothe stake section to an objectionable degree, the upper end of the upperstake section 6 is preferably closed by means of a hinged cover or cap15 adapted to be readily opened to fa 18. This load binding chain isadapted to be extended to the slide block 17 of another similar stakemounted upon the opposite side of the car directly opposite the presentstake shown, as is generally well known in the art. As the slide blocksare freely slidablo in a vertical direction, it is evident that the loadbinding chains 18 may be readily adjusted vertically to the height ofthe load relative to the upper stake section.

In use, assuming that the stake is collapsed as shown in Figure 4, thecover 15 is open and by inserting the fingers into the I upper end ofthe stake section 6, the handle 10 may be grasped. By pulling upwardlyupon the rod 9, the latch bolts 7 may be positively fully retracted soas to offer no frictional resistance whatever to the elevation of thestake section 6. As soon as the stake section 6 reaches its upward limitof movement to operative position, the bolts '7 will be projected bysprings 12 into the openings 14, thus effectively sustaining the section6 in elevated position. The cover 15 is then closed and slide 17 isadjusted to the desired elevation in slots 16. When it is desired tocollapsethe stake, the cover 15 is again opened and the rod 9 pulledupwardly so as to release the catch bolts 7, and while exerting anupward pull upon the rod 9, the stake section 6 is forced downwardlyinto the lower stake section 5 to the position of Figure 4:. As thestake section 6 is slightly longer than the stake section 5, the cover15 will not interfere with lowering of said stake section 6, and bymaking the latter slightly longer, the necessity for re moval of slideblock 17 may be avoided.

From the foregoing description it is believed that the construction andoperation as well as the advantages of the present invention will bereadily understood and appreciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope ofthe in vention asclaimed.

What I claim as new is 1. A telescopic car stake comprising hollow lowerand upper sections slidably fitted one within the other, opposedhorizontal sliding latch bolts mounted in the lower por tion of theupper section and engageable with the lower stake sectionto hold theuppersection in extended position, and a vertical pull rod within theupper stake section operable for releasing said latch bolts.

2. A telescopic car stake comprising hollow lower and upper sectionsslidably fitted one within the other, opposed horizontal sliding latchbolts'mounted in the lower por tion of the upper section and engageablewith the lower stake section to hold the upper section in extendedposition, a' vertical pull rod within the upper stake'section operablefor releasing said latch bolts, said pull rod terminating in the upperend of the upper stake section, and a cover for theupper end of theupper stake section, movable to uncover the latter and permit accesstothe pull rod.

3. A telescopic car stake comprising hollow lower and upper'sectionsslidably fitted one within the other, opposed horizontal sliding latchbolts mounted in the lower portion of the upper section and engageablewith the lower stake section to hold the up per section in extendedposition, a vertical pull rod within the upper stake section operablefor releasing said latch bolts, and toggle link connections between theinner ends of the latch bolts and said pull rod.

4. A telescopic car stake comprisinghollow lower and upper sectionsslidably fitted one within the other, means to releasably hold the uppersection in extended position,

said upper section having an elongated yer tical slot in the inner sidethereof extending substantially from top to bottom of the same, anH-shaped slide block slidably engaging the wall of said upper section atoppositesides of said slot and movable in the latter for verticaladjustment, and a load binding chain attached to said slide block.

5. A telescopic car stake embodying hollow lower and upper sectionsslidably fitted one within the other, spaced superposed pairs of opposedspring-projected latch, bolts mounted for horiozntal slidingmovement inthe lower part of said upper section, a vertical operating rod in saidupper section terminating near the top of the latter, and toggle linksconnecting the inner ends of said latch bolts to said operating rod, thelower section having openings in the upper portion thereof to receivesaid bolts for holding the upper section in extended position.

In testimony whreeof I aflix my signature.
